Page 3: Chapter 1 Introduction
Chapter 1 Introduction Important Safety, Care and Handling Instructions 1. Before starting, take a few minutes to read this manual, read all of these instructions and save this manual for later reference. 2. Protect the Disk Array from extremely high or temperatures. Let the Disk Array warm (or cool) to room temperature before using it. -
Page 4: Operating Environment
Operating Environment When selecting a suitable working location, please consider : - Ventilation - Temperature - Dust and dirt - Electromagnetic and Radio Frequency Interference. - Security The selected location should provide at least six inches of open space around the Disk Array cabinet for proper air fl ow. -

For more detailed information, please refer to the technical specifi cations appendix at the end of this manual .Your Disk Array includes the following features : Easy Operation As everyone knows, conventional Disk Arrays are designed for experienced computer specialists. -
Page 6: General Raid Concepts
General RAID Concepts General RAID Concepts Correct installation of the disk array requires an understanding of RAID technology and the concepts described in this section. Defi nition RAID is an acronym of Redundant Array of Independent Disks .A RAID is a Disk Array in which part of the storage capacity is used to record redundant information about the user data stored on the remainder of the storage capacity. - Page 7 Chapter 1 Introduction RAID LEVELS RAID Level 0 : “ Disk Striping “ High I/O Performance • Improved I/O performance is the major reason for using RAID level 0. No protection is provided against data loss due to member disk failures. A RAID level 0 array by itself is thus an unsuitable storage medium for data that can not easily be reproduced, or for data that must be available for critical system operation.

RAID LEVELS (CONT’D) RAID LEVELS (CONT’D) RAID Level 1 : “ Disk Mirroring “ High Data reliability RAID level 1 provides both very high data reliability and continued data availability in the event of a failure of an array member. When a RAID level 1 member disk fails, array management software simply directs all application requests to the surviving member. -

Chapter 1 Introduction RAID LEVELS (CONT’D) RAID LEVELS (CONT’D) RAID Level 3 : “Parallel Transfer Disks with Parity “High Data Reliability & Highest Transfer Capacity RAID Level 3 technology use a dedicated parity disk to store redundant information about the data on several data disks. -

RAID LEVELS (CONT’D) RAID LEVELS (CONT’D) RAID Level 5 : “Independent Access Array with Rotating Parity “High Data Reliability & Transfer Capacity When RAID Level 5 technology is combined with cache memory to improve its write performance, the result can be used in any applications where general purpose disks would be suitable. For read only or read mostly application I/O loads, RAID Level 5 performance should approximate that of a RAID Level 0 array. -
Page 11: Summary Comparison Of Raid Levels
Chapter 1 Introduction SUMMARY COMPARISON OF RAID LEVELS RAID Common Level Name Disk Striping Mirroring Parallel Transfer Disks with Parity Independent Access Array with Rotating redundant Information is Parity Description Data distributed across the disks in the array. No redundant Information provided. -
Page 12: Supported Raid Levels
SUPPORTED RAID LEVELS RAID Level "Disk Striping" , block striping is used, which yields higher performance than with the individual disk drives. * There is no redundant function. "Disk Mirroring" , Disk drives are mirrored , All data is 100% duplicated on each equivalent disk drives. -
